We purchased a seasonal beach house in late 2020. The water is turned on in April and off late Oct. We renovated the interior in late 2020. We plan to rent it for 2 months in 2021 and use it ourselves some of the time. It had been rented by the previous owner for similar time periods. For tax purposes when is it "put into service"? And is this date the same every year or will it be January 1 after this first year? I am trying to determine how to calculate expenses against rental income: ratio of our use to rental use? Or just expenses incurred during the rental time? We do have mortgage on the property. It will sit empty for the balance of the year.
